*Mom bought one big watermelon for the hot day. My brother was so thirsty that he wanted half of the watermelon. Mom cut the watermelon into two sections and gave my brother the larger section. Then she asked: ”Is this half of the watermelon that you wanted?” My brother said: “yes, yes. ” *

*“No. When a watermelon is cut into halves, your section and your brother’s should be the same big.”*

*“Oh! Half a watermelon means that the two sections of the watermelon are the same. Brother, next time, I will make sure that mom cuts the watermelon into two same sections so that you and I each can have a section of the same big.”*

**1/8 of a stick is cut off. If If another stick that is 15 inches long is glued to the remaining part of the first stick, the first stick will be 1/2 longer than its original length. What is the original length of the first stick?**

**In this problem, you need to find the match between the fractional part and the amount in it ( if you do not know about these terms, please go to**** ****Word Problem: Detailed Explanations of Reasoning and Solving Strategies Volumes 11-A, 11-B and 12)**

**15 inches not only has covered 1/8 of the stick that is cut off but also makes the the stick 1/2 longer so we can say that 15 inches match the sum of the fractional parts: 1/8 and 1/2.**

**We divide the sum of the fractional parts: 1/8+1/2=5/8 into the amount that matches it: 15 inches to find the amount in 1, which is the length of the original stick: ( please go to the books ****Word Problem: Detailed Explanations of Reasoning and Solving Strategies Volumes 11-A, 11-B and 12 ****for more detailed explanation):**

**15÷5/8=24 inches**

**The original stick is 24 inches. **

Now there are 5 locks and 5 keys left.****Use the 5 keys to try another lock and at most 4 tries are required before the lock finds its key. Move the second set of key and lock out of the groups. Now there are 4 locks and 4 keys left.****Use 4 keys to try another lock and at most 3 tries are required before the lock finds its key. Move the third set of key and lock out of the groups. Now there are only 3 locks and 3 keys left.****Use the 3 keys to try another lock and at most 2 tries are required before the lock finds its key. Now more the fourth set of key and lock out of the groups. Now there are only 2 locks and 2 keys left.****Use the 2 keys to try one of the remaining locks and at most 1 try is required for the lock to find its key. Move the 5th set of key and lock out of the groups. Now there are only 1 key and one lock left and they should be one set.**

**How many tries are there from the above steps?**

**5+4+3+2+1=15 tries**
